My internet cuts out constantly. I have called Comcast Xfinity over 15 times in the past month about this issue and have had three technicians visit recently (including two in the past 1-2 weeks). Both times, the technicians thought they had identified and fixed the problem. However, the problem persists. I have wasted countless hours on the phone with customer service, going through the same steps, over and over and over.   Comcast customer service has been very unhelpful (however, the technicians who have visited have all been great). They say they cannot schedule another visit because it is an "internal" issue - however, the last technician who visited measured the signal *inside* my house and didn't find any problems. Instead, he said that Comcast made an error when our neighbors (who just moved in) recently connected their cable TV. Every time I call customer service, it is a different story.   Anyway, I thought I would try to debug the problem here. If anyone can help at all, I would really appreciate it. I will copy my modem log below, but if there's anything else that would be useful, please let me know. We also purchased a new wireless router, but this didn't fix the problem. Thank you.   May 22 2020 00:10:33 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 22 2020 00:10:22 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 22 2020 00:06:31 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:18:49 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:18:29 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:18:29 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:17:34 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:17:29 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:04:15 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:04:10 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:03:56 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:03:56 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 23:03:43 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 18:50:39 5-Warning Z00.0 MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; Jan 01 1970 00:00:22 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; Jan 01 1970 00:00:18 6-Notice N/A Cable Modem Reboot due to power reset ;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.0; May 21 2020 18:46:44 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 18:46:24 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 18:36:35 3-Critical R02.0 No Ranging Response received - T3 time-out;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0; May 21 2020 18:35:25 3-Critical R07.0 Unicast Ranging Received Abort Response - initializing MAC;CM-MAC=20:3d:66:05:25:77;CMTS-MAC=00:87:31:90:0a:3f;CM-QOS=1.1;CM-VER=3.0;   Here is my signal information:   Downstream Bonding Channel Value Channel ID 33  34  35  36  37  38  39  40  Frequency 651000000 Hz  657000000 Hz  663000000 Hz  669000000 Hz  675000000 Hz  681000000 Hz  687000000 Hz  693000000 Hz  Signal to Noise Ratio 35 dB  35 dB  35 dB  34 dB  33 dB  32 dB  33 dB  34 dB  Downstream Modulation QAM256  QAM256  QAM256  QAM256  QAM256  QAM256  QAM256  QAM256  Power Level The Downstream Power Level reading is a snapshot taken at the time this page was requested.
